Wazdan has a well-established signature style by now, and they also have many different slot series going for them. This one started with 9 Coins™, which has already been released in both a Grand Gold and 1000 edition, and 12 Coins™ is a bigger and bolder follow-up release in the range. Calling it “bigger and bolder” is technically correct, at least compared to the original, but the difference isn’t as massive as that expression might give you the impression of.
The two installments are very similar, in fact, but you get a larger 4x3 sized grid in 12 Coins™. You cannot win anything in the base game, as before, so your sole aim is to trigger the Hold the Jackpot Bonus Round. The Cash Infinity™ symbol can help you out in that regard, and the feature comes with jackpot symbols, collector multiplier symbols, mystery and mystery jackpot symbols, as well as a full grid 750x Grand Jackpot.
There are no payouts in the base game, and you need to fill the 4 positions on the middle row with any kind of bonus symbols to trigger the Hold The Jackpot Bonus Round. You can land Cash Infinity symbols in the base game though, and these symbols are sticky until the end of the next bonus round. They come with values between 5x and 10x your stake, and landing them on the middle row increases your bonus round chances.
All triggering bonus symbols are sticky on an otherwise cleared Bonus Round grid, and it comes with 12 positions just like the base game. You start with 3 respins, and each new bonus symbol that lands becomes sticky as well. This resets the respins tally to 3 each time, and the feature ends when you either fill the grid with bonus symbols or run out of respins.
You can land regular cash symbols that award prizes between 1 and 5 x the stake, while the Mini, Minor, and Major jackpot symbols pay 10x, 20x, and 50x your stake, respectively. The Collector symbol accumulates the value from both Cash And Cash Infinity symbols, and boosts the total amount by a random multiplier of x1 to x20.
You can land a regular Mystery Symbol, and it will turn into any other bonus symbol type randomly as the feature ends. It cannot turn into the Cash Infinity symbol, however. The Jackpot Mystery Symbol turns into 1 of the 3 above-mentioned jackpots as the feature ends, and all winnings are summed up in the end. If you fill the screen with bonus symbols, however, you win the 750x Grand Jackpot instead.
